A robust dune system is one of the principal factors in the protection of recreational and residential property within barrier islands. Storm surge from significantly large storm events may remove some or all of the dunes during overwash...
High Resolution Microclimate Study of Hollow Ridge Cave: Relationships Between Cave Meteorology, Air Chemistry, and Hydrology and the Impact on Speleothem Deposition
Long term, near continuous, in situ monitoring of cave meteorology, cave aerochemistry, and surface meteorology allows quantitative assessment of cave ventilation and the effect on CO₂ outgassing from cave systems. Because advances in...
Ocean wind vectors from the SeaWinds scatterometer on QuikSCAT and GOES imagery are used to develop an objective technique that can detect and monitor tropical disturbances associated with the early stages of tropical cyclogenesis in the...
A new objective technique is used to analyze monthly mean gridded fields of air and sea temperature, scalar and vector wind, specific humidity, sensible and latent heat flux, and wind stress over the Indian Ocean. A variational method...
The use of chemical tracers to understand ecosystem interactions in the marine environment has gained increasing popularity over the past three decades. Carbon isotope abundances in organic matter sources in the marine system vary...
ABSTRACT High-resolution biostratigraphic data were collected from two cores drilled in 2007 and 2009 by the United States Geological Survey at the South Dover Bridge (SDB) and the Cambridge-Dorchester (Cam-Dor) Airport in eastern...
Improving lightning cessation forecasts is important to operations of the 45th Weather Squadron (45WS) at Kennedy Space Center (KSC). If lightning advisories can be cancelled closer to the time that cessation actually occurs without...
Large amplitude internal waves are a long recognized feature of the South China Sea. Remote sensing imagery often shows the sea-surface manifestation of these waves as they radiate from the Luzon passage into the deep water of the South...
Warm seclusions are large midlatitude storms that have the potential to substantially influence the turbulent heat fluxes and global energy budget. These storms have not been previously investigated from an energy and flux perspective....
The δ13C value of foliage respiration has been considered a constant in the past and modeling efforts have assumed that the δ13C value of foliage respiration is constant and is directly related to substrate without any fractionation....
Naturally-occurring radioisotopes are ubiquitous in nature, and as such, there are many opportunities for researchers to use them as environmental tracers. Their associated radioactive decay rates provide an inherent time clock that...
Satellite and ground-based instrumentation, such as radar, lidar and radiometers, have the capability of remotely detecting water, graupel, ice and snow particles in the atmosphere. The detection and characterization of liquid water in...
Rates of U(VI) release from two field-aggregated and contaminated composite sediments were collected from the seasonally saturated lower vadose zone of the US Hanford 300 Area were examined in stirred flow-cell reactors. Kinetic U(VI)...
The Asian summer monsoon is a dominant feature of the global circulation. The upper-level anticyclone (ULAC) associated with the Asian summer monsoon circulation stands out vividly in satellite observations of trace gases. The ULAC also...
The goal of this investigation was to determine whether highly accurate sampling and dating methods could be employed to develop a high-resolution history of barrier evolution and sea-level change. The focus of the study was St. Vincent...
How much warmer is the ocean surface than the atmosphere directly above it? Part 1 of the present study offers a means to quantify this temperature difference using a nonlinear one-dimensional global energy balance coupled ocean...
The National Aeronautics and Space Administration (NASA) conducted the Arctic Research of the Composition of the Troposphere from Aircraft and Satellites (ARCTAS) mission during 2008 as a part of the International Polar Year (IPY). The...
This study presents a new method for assimilating lightning data into numerical models that is suitable for cloud-resolving scales (e.g., 3 km). The study utilized data from the Earth Networks Total Lightning Network at 9 km grid spacing...
ABSTRACT The Ocean Drilling Program (ODP) Leg 154 in the western equatorial Atlantic cored Paleocene - Holocene strata at Site 929 on the Ceara Rise. The calcareous nannofossil biostratigraphy of the Oligocene - lower Miocene sequence at...
One way to slow down global warming is to reduce the amount of carbon dioxide released into the atmosphere by capturing carbon dioxide from point sources (e.g., power plants) and storing it out of contact with the atmosphere. One storage...
The Impacts of Macrobenthos on the Rates and Pathways of Organic Matter Mineralization in Two Coastal Marine Ecosystems of the Southeastern United States
Coastal ecosystems are among the most productive in the world, and they serve as an invaluable resource to society. Despite many decades of biogeochemical research in the coastal zone, carbon and nutrient budgets remain uncertain largely...
Tropical cyclone (TC) forecasts rely heavily on output from numerical models. Each model in the suite of models used by forecasters has its own strengths and weaknesses. Some research has investigated the skill of the various models with...
Fundamental to an understanding of El Niño/Southern Oscillation climate fluctuations is an understanding of the interannual equatorial Pacific surface flows, which advect the surface waters and change the sea surface temperature. While...
Using a suite of high resolution models, the forecast skills of the superensemble for precipitation and 2-meter temperature over the continental United States and North America are shown. In this study, models and/or gridded fields such...
Quantifying and Differentiating Impacts of Climate Variation, Instream Modification, and Anthropogenic Land Use Change on River Hydrological and Geomorphologic Processes
A proactive strategy to alleviate increasing flood damages is to better understand flood pattern changes and pinpoint physical causes that are responsible. To identify the physical causes responsible, a major obstacle lies at...
Studies on the timing of cloud-to-ground (CG) lightning initiation have been conducted for various regions of the United States. There is evidence that in-cloud (IC) flashes often precede CG flashes by 10 or more minutes in the Great...
Energy is introduced into the oceans primarily at large scales by means of wind, tides and surface buoyancy forcing. This energy is transferred to the smaller mesoscale eld through the geostrophic instability processes. The mesoscale eld...
This study uses the high-resolution infrared radiation AVHRR (Advanced Very High Resolution Radiometer)-only and microwave radiation AMSR (Advanced Microwave Scanning Radiometer)+AVHRR sea surface temperature (SST) datasets to analyze...
Dissolved organic matter (DOM) is well known for its strong binding capacity for trace metals. In order to better predict the role of DOM in the speciation and transport of trace metals in the environment capillary electrophoresis (CE), ...
The role of mesovortices in the eyewalls of sheared unstable, high-Rossby number vortices is investigated. A high-resolution numerical model is used to simulate dry vortices in an attempt to unite ideas from previous works. The...
Coherent Tropopause Disturbances (CTD's) have been observed to play a central role in both extratropical cyclogenesis and the dynamics of jet streaks. Recent observational studies have quantified the existence of CTD's by locating...
